Mdlmkr, It sounds like you have a video card problem. Do you know what your card is? There is some new info on the Surfware web page. Click the support tab/Surfcam FAQ's for a lot of info on video stuff. You'll need to log in to get to those pages, which should be no problem if you're on maintenance.
I have Surfcam 2005, but haven't used it at work yet, because my machine apparently doesn't have the right video card. I have an ATI Fire GL2 with 64 megs of ram on it, and Surfcam 2005 won't run on it. I can run it at home, but I have twice the box that I have at work. nVIDIA cards seem to be the best application for CAD/CAM. I just got one for $269 at Fry's. The Quadro series are $350-$450. I hope I can convince IS to get me one!
